【摘要】 μC/OS-Ⅱ是一种源代码开放的实时嵌入式操作系统,支持抢占式固定优先级的任务调度方法。扩展μC/OS-Ⅱ的任务调度机制,使之支持设定同优先级任务,并实现同优先级任务时间片轮转,高优先级任务可抢占的任务调度方式。μC/OS-Ⅱ中任务调度机制的改进方法既保留原调度机制的高度实时性,也增加任务调度方式的灵活性,并且实现简单、有效。更多还原

【Abstract】 The μC/OS-Ⅱ is a real-time embedded operating system which source code is open and it sustains preemptive machine-made PRI task scheduler method.Through extending μC/OS-Ⅱ’s task scheduler mechanism,makes it sustain setting same PRI task,realizes same PRI task time slice cycle,high priority preemptive task scheduler method.The improved μC/OS-Ⅱ task scheduler mechanism not only holds its original high real time nature,but also enhances its scheduler method agility,and also makes it simple and efficiency.更多还原
